A damped resonant piezoelectric alerting device (600) includes a motional mass (130), a damping element (136, 156) magnetically coupled to the motional mass (130) and a piezoelectric actuator (100) which is constrained to an actuator mount (132) at a first end and coupled to the motional mass (130) at a second end. The piezoelectric actuator (100) responds to a control signal (108, 110) to generate an alternating out-of-plane movement (812, 814) of the motional mass (130) at an amplitude (412, 414). The alternating out-of-plane movement (812, 814) of the motional mass (130) is transformed into tactile energy to provide a tactile alert about a resonant frequency (608). The amplitude (412, 414) of the out-of-plane movement (812, 814) of the motional mass (130) is controlled by the damping element (136, 156). The alternating out-of-plane movement (812, 814) of the motional mass (130) is also transformed into acoustic energy to provide an audible alert above the resonant frequency (608).
